How many moles of aluminum are present in 856g of aluminum sample?
To determine the number of moles of aluminum present in 856g, you need to divide the mass by the molar mass of aluminum. The molar mass of aluminum is approximately 26.98 g/mol. So, 856g ÷ 26.98 g/mol ≈ 31.7 moles of aluminum are present in 856g.
How can one test for aluminum in a sample?
One can test for aluminum in a sample by using methods such as atomic absorption spectroscopy, inductively coupled plasma spectroscopy, or colorimetric tests. These methods involve analyzing the sample for the presence of aluminum ions or compounds.
Can you identify the molecule present in this sample?
The molecule present in this sample is insert molecule name.
How many lb-moles of substance are present in the given sample?
To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.
How many molecules in aluminum phosphate?
To calculate the number of molecules in aluminum phosphate, we need to know the mass of the sample. Given the mass of aluminum phosphate, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules in the sample.
How many atoms of aluminum are there in a sample of aluminum sulfide with a mass of 100 g?
Aluminum sulfide has a molar mass of 150.16 grams per mole. This means there are 0.666 moles present, or 4.01 E23 molecules. Each molecule of Al2S3 has 2 aluminum atoms, so there are 8.02 E23 atoms of aluminum present.

What Metals are in aluminum?
Aluminum is a pure substance. It is the thirteenth element in the periodic table. Aluminum is the only metal in a sample of aluminum, unless it contains impurities.
How many lb-moles of substance are present in the given sample?
To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.

Why would having a larger sample size be a better idea than having a samll sample size when doing an experiment?
less bias and error occur when sample size is larger
Why is having a larger sample size be a better idea than having a small sample size when doing a experiment?
1. Better chance of uniform sample. 2. Material for confirmations if needed.
